How many valence electrons does BeCl2 have?

Answer 1

Since Be is in the 2nd group, it should have 2 valence electrons and Cl should have 7 (in 7th group), and since there is 2 Cl, then there is 14. Add 14 Cl electrons and 2 Be electrons to get 16 electrons (valence, not total)

Answer 2

BeCl2 has 4 valence electrons. Beryllium has 2 valence electrons, while each chlorine atom contributes 7 valence electrons.
